We delve into the horrifying crimes of a convicted serial predator whose reign of terror culminated in the brutal murders of the Groene family in 2005. We’ll explore Duncan’s dark past and the stalking and execution-style killings that led to the abduction of Shasta and Dylan Groene. We talk about managing our consumption of evil things in the world, the impact that has on our parenting, and we unravel how media efforts helped bring one of the most dangerous offenders in U.S. history to justice.
